ARM: 6382/1: Remove superfluous flush_kernel_dcache_page()
Since page cache pages are now considered 'dirty' by default, the cache flushing is handled via __flush_dcache_page() when a page gets mapped to user space. Highmem pages on VIVT systems are flushed during kunmap() and flush_kernel_dcache_page() was already a no-op in this case. ARCH_HAS_FLUSH_KERNEL_DCACHE_PAGE is still defined since ARM needs specific implementations for flush_kernel_vmap_range() and invalidate_kernel_vmap_range().
